Moved the stuff that is common to all directories of pkgsrc into its own

file. Now "make help" can be called from the top-level directory,
avoiding to parse lots of buildlink3.mk files just to get some help.

+# System-provided variables:

+# RUN
+#	This variable can be prepended to all shell commands that should
+#	not be printed by default, but when PKGSRC_DEBUG_LEVEL is
+#	non-zero. It also re-adds the error checking that has been
+#	removed in 2004 to make bmake conform to POSIX.
